Gait assessments in standardized settings, as part of the clinical follow-up of children with cerebral palsy (CP), may not represent gait in daily life. This study aimed at comparing gait characteristics in laboratory and real life settings on the basis of multiple parameters in children with CP and with typical development (TD). Fifteen children with CP and 14 with TD wore 5 inertial sensors (chest, thighs and shanks) during in-laboratory gait assessments and during 3 days of daily life. Sixteen parameters belonging to 8 distinct domains were computed from the angular velocities and/or accelerations. Each parameter measured in the laboratory was compared to the same parameter measured in daily life for walking bouts defined by a travelled distance similar to the laboratory, using Wilcoxon paired tests and Spearman's correlations. Most gait characteristics differed between both environments in both groups. Numerous high correlations were found between laboratory and daily life gait parameters for the CP group, whereas fewer correlations were found in the TD group. These results demonstrated that children with CP perform better in clinical settings. Such quantitative evidence may enhance clinicians' understanding of the gap between capacity and performance in children with CP and improve their decision-making.
在标准化环境中进行步态评估，作为脑瘫（CP）儿童临床随访的一部分，可能无法代表日常生活中的步态。本研究旨在比较 CP 儿童和典型发育（TD）儿童在实验室和现实生活环境中的步态特征，基于多个参数。15 名 CP 儿童和 14 名 TD 儿童在实验室步态评估期间和日常生活中的 3 天内佩戴了 5 个惯性传感器（胸部、大腿和小腿）。从角速度和/或加速度计算了属于 8 个不同域的 16 个参数。使用 Wilcoxon 配对检验和 Spearman 相关性，将实验室测量的每个参数与日常行走过程中测量的相同参数进行比较，行走过程通过类似于实验室的行进距离来定义。两组中，大多数步态特征在两种环境中均存在差异。CP 组中，实验室和日常生活中的步态参数之间存在大量高度相关性，而 TD 组中相关性较少。这些结果表明，CP 儿童在临床环境中表现更好。这种定量证据可以增强临床医生对 CP 儿童能力和表现之间差距的理解，并改善他们的决策能力。
